Features / Enhancements	Name	Description	Scope
vSTP UDR connection redundancy feature	POR 33883528	Prior to this release, if there is one Connection Group on vSTP NO with default priority set to 10, there was no provision to configure one interface as the priority route and another interface as the secondary (when the primary interface fails). This feature provides redundancy between local site and remote site for Mobile Number Portability (MNP), where the priorities can be set using the the following three parameters provided in connection group for UDR lookup on vSTP NO GUI. STPSvcGroup=30 (default value) indicates highest priority STPSvcBackGroup=20 indicates a lesser priority STPSvcSpareGroup=10 indicates a much lesser priority For more information, see Oracle Communications Diameter Signaling Router Mobile Number Portability User Guide.	New feature
vSTP ITUI-S/ITUN-S support for MTP Screening feature	POR 32948876	Starting with this release, vSTP uses the TCAP Opcode Tag Based Routing to find Operation Code Tag in all supported ITU TCAP messages except ABORT. If messages have Opcode Tag value anything other than Local(0x02) or Global(0x06), then it is considered as Invalid. For more information, see Oracle Communications Diameter Signaling Router vSTP User Guide.	New feature
